摘　　要：目的 分析3.0T磁共振成像在诊断膝关节半月板周缘性脱位中的价值及准确率。方法 选入本院2023年1月至11月收治的疑似膝关节半月板周缘性脱位患者78例,均进行多层螺旋CT和3.0T磁共振成像检查,以关节镜检查结果为“金标准”,对比3种方式的检出率和诊断效能。结果 多层螺旋CT的阳性和阴性预测值分别为90%和43%,灵敏度、特异度、准确度分别为74%、71%、73%;3.0T磁共振成像的阳性和阴性预测值分别为95%,70%,灵敏度、特异度、准确度分别为90%、82%、88%;联合检查的阳性和阴性预测值分别为98%、94%,灵敏度、特异度、准确度分别为98%、94%、97%;3.0T磁共振成像诊断的准确度和灵敏度都比多层螺旋CT高,差异有统计学意义(P<0.05)。结论 3.0T磁共振成像在诊断膝关节半月板周缘性脱位中的价值高,准确率高于多层螺旋CT检查,但是比联合检查低。Objective To analyze the value and accuracy of 3.0T magnetic resonance imaging in diagnosising knee meniscus peripheral dislocation.Methods A total of 78 patients with suspected meniscus peripheral dislocation of the knee admitted to our hospital from January to November 2023 were selected.All patients underwent multi-slice spiral CT and 3.0T magnetic resonance imaging.The arthroscopy results were taken as the"gold standard",and the detection rate and diagnostic efficiency of the three methods were compared.Results The positive and negative predictive values of MSCT were 90%and 43%,respectively.The sensitivity,specificity,and accuracy were 74%,71%,and 73%,respectively.The positive and negative predictive values of 3.0T MRI were 95%and 71%respectively,and the sensitivity,specificity,and accuracy were 90%,82%,and 88%respectively.The positive and negative predictive values of combined examination were 98%and 94%respectively,and the sensitivity,specificity,and accuracy were98%,94%,and 97%respectively.The diagnostic accuracy and sensitivity of 3.0T magnetic resonance imaging were higher than those of multi-slice spiral CT(P<0.05).Conclusion The value of 3.0T MRI in the diagnosis of knee meniscus peripheral dislocation is high,and the accuracy rate is higher than that of multi-slice spiral CT,but lower than that of combined examination.
